How many non-polar bonds are present in a molecule of $C_1{H}_{3}OH$ (methanol)?

• A. $3$
• B. $4$
• C. $2$
• D. $1$

Answer: (A)

Verified step by step guidance

1. Identify the molecular structure of methanol (CH3OH). It consists of one carbon atom bonded to three hydrogen atoms and one hydroxyl group (OH).
2. Determine the types of bonds present: C-H bonds, C-O bond, and O-H bond.
3. Recall that non-polar bonds occur between atoms with similar electronegativities, resulting in an even distribution of electron density. Polar bonds occur between atoms with different electronegativities.
4. Evaluate each bond: C-H bonds are generally considered non-polar because carbon and hydrogen have similar electronegativities; C-O and O-H bonds are polar due to the significant difference in electronegativity between oxygen and carbon or hydrogen.
5. Count the number of non-polar bonds, which are the C-H bonds in methanol. Since there are three C-H bonds, the number of non-polar bonds is three.
